Abstract

An apparatus comprises at least one processing device configured to identifying nodes of a distributed storage system and power distribution units in an information technology infrastructure environment, and to generate a mapping data structure of mapping identifying power outlets of the power distribution units that the nodes are connected to, where the mappings for a given node are generated by triggering an operation which temporarily reduces power consumption and determining which powers outlets report a change in power consumption in conjunction with the triggered operation. The at least one processing device is also configured to create, based at least in part on the generated mapping data structure, fault sets for the distributed storage system, each of the fault sets comprising a subset of the nodes of the distributed storage system having resiliency to one or more power-related failure conditions.

Dependent claims

An apparatus comprising:

at least one processing device comprising a processor coupled to a memory;
the at least one processing device being configured:
to identify a set of nodes of a distributed storage system deployed in an information technology infrastructure environment;
to identify a set of power distribution units in the information technology infrastructure environment;
to monitor power consumption by power outlets of each power distribution unit in the set of power distribution units;
to generate a mapping data structure comprising mappings identifying ones of the power outlets of the set of power distribution units which each node in the set of nodes of the distributed storage system is connected to, wherein generating the mappings for a given node in the set of nodes of the distributed storage system comprises (i) triggering an operation on the given node which temporarily reduces power consumption of the given node and (ii) determining, based at least in part on the monitored power consumption, which power outlets of the set of power distribution units report at least a threshold change in power consumption in conjunction with the triggered operation on the given node;
and
to create, based at least in part on the generated mapping data structure, two or more fault sets for the distributed storage system, each of the created two or more fault sets comprising a subset of the set of nodes of the distributed storage system having resiliency to one or more power-related failure conditions.
